The invention discloses a rural old road reconstruction construction method, and relates to the technical field of road construction, the rural old road reconstruction construction method comprises an old road section, and the method comprises the following steps: S1, digging a step-shaped first splicing groove and a step-shaped second splicing groove in the two sides of the old road section to form a new roadbed; s2, steel wire meshes are laid at the groove bottoms of the first splicing groove and the second splicing groove, and one sides of the steel wire meshes are inserted into the groove walls of the first splicing groove and the second splicing groove; s3, a retaining wall is poured on the side, away from the old road section, of the new roadbed through concrete; s4, laying 4% cement stabilized graded broken stones on the first splicing groove to form a subbase layer; s5, 5.5% cement stabilized graded broken stones are laid on the subbase layer and the groove bottom of the second splicing groove to form a base layer; s6, an anti-crack patch is attached to the joint of the base layer and the old road section, and asphalt concrete is laid on the old road section and the base layer to form a surface layer; and S7, paving asphalt mastic macadam on the surface layer to form a new pavement. New and old road sections can be more stable.
本申请公开了一种农村旧路改建施工方法，涉及道路建设技术领域，包括旧路段，包括一下步骤：S1、在旧路段两侧挖出呈阶梯状的第一拼接槽和第二拼接槽形成新路基；S2、在第一拼接槽和第二拼接槽的槽底铺设钢丝网，将钢丝网的一侧插入第一拼接槽和第二拼接槽的槽壁；S3、在新路基远离旧路段的一侧使用混凝土浇筑挡墙；S4、在第一拼接槽上使用4%水泥稳定级配碎石铺设形成底基层；S5、在底基层和第二拼接槽的槽底上使用5.5%水泥稳定级配碎石铺设形成基层；S6、在基层与旧路段的连接处贴上抗裂贴，并在旧路段和基层上使用使用沥青混凝土铺设形成面层；S7、在面层上使用沥青玛蹄脂碎石铺设形成新路面。本申请能够使新旧路段更加稳固。
